IMPROVEMENT IN STREET AND PARK LAMPS.

Specification forming part of Letters Patent No. 189,514, dated April10, 1877 application filed March 21. 1877.

To all whom it may concern:

Be it known that 1, JAMES STIM'PSON, of Baldwinsville, county ofWorcester, and State of Massachusetts, have invented an Improvement inStreet and Park Lamps, of which the following is a specification:

This invention relates to improvements in street and park lamps; andconsists in a swiveling lantern-cage having its supportinglever pivotedto a post, so that the lever and lantern may swing from their uprightpositions to a position where the lamp or illuminating medium may beplaced into or re moved from the lantern, thereby obviating the use of aladder.

Figure 1 represents one of my improved street-lamps in side elevation.Fig. 2 shows the lantern-cage and lever swung down, an Figs. 3 and 4show modifications.

The post a may be made of iron or wood, and may be of any suitableheight and pattern.

The lever b, to support the lantern-cage 0, has at top a fork, d, towhich the lantern is swiveled.

This lever is pivoted at e, and, as shown in Figs. 1 and 2, it has aweight,f, to counterbalance the weight of the lantern.

The lantern may be made of any suitable shape or material, and mayreceive a lamp containing any usual burning material or a candle.

The lever and lantern are locked in upright position by means of alocking device, the main part of which, in this instance, is shown asattached to the post.

This locking device is composed of a slide, g, provided with bars orportions to be engaged by a hook, it, on the lever, and a hook, i, onthe lantern, when the latter is in upright position, as shown in Fig. 1.

a stud, l, that enters the bent lower end of the slide.

Instead of the devices shown as employed to hold the lever and lanternin upright position, I may employ a reciprocating spring-held pin, toenter ahole in the lever, and a second one to fasten the lantern and itsholding-fork together.

Instead of using the counterbalancingweight, as shown, I may attach tothe lower end of the lever (it terminatingjnst below the pivotal pointe) a cord, m, which in turn is adapted to be connected with either astrong spiral spring or a weight. (Not shown.)

This lever may be provided with teeth 11., adapted to engage with and tobe operated by means of a pinion, 0, turned by a handle, 19, applied tothe shaft of the binion.

A pawl, r, acting against a ratchet, prevents the lever from moving backtoo far.

I may fasten to the lever a pivot, 8, adapted to fit into openings inthe post, and by applying a handle to the pinion, as at t, the lantern(the lever being weighted or otherwise counterbalanced) may be raised orlowered in the are of a circle.

I claim 1. The combination, with a lamp-post, of a pivoted lever andlantern, substantially as and for the purpose described.

2. The pivoted lever, lantern, and post, in combination with a lockingdevice to hold the lever in an upright position.

3. A locking device, in combination with a lantern-cage and itscarrying-lever, to operate substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

JAMES STIMPSON.
